This study aimed to identify the factors of failure in cases where there was feasibility but was not successful in commercializing technology. For the study, 92 feasibility reports for new technologies were collected, and among these 4 studies that showed definite failure in commercialization of technology were analyzed in depth. Further analysis was based the factors pointed out by previous frameworks such as 1) discussion on success or failure in commercialization of technology, 2) that of venture company, and 3) valuation of technology studies. Previous studies pointed out success and failure factors as lack of funding, uncontrollable accidents, managing ability, inability for mass production and so forth, which had little difference to the pre-feasible evaluation of four cases. However, real reason was the lack of understanding technologies such as composition of technologies, production technologies required by stages, and lack of understanding of floor technologies. The misunderstandings were occurred regardless of CEO's experience and expertise. We did not touch the evaluation model of pre-feasibility studies, although we dealt with the failure of the pre-studies. The reason we do not generalize the results of this study is the fact that we dealt with only small cases.

This study aims to explore the influencing factors and the process of enhancing science self-efficacy (SSE) and to lay the foundation in understanding science self-efficacy of students. The ten categories related to the science self-efficacy were derived through the coding of the interview data based on the grounded theory and paradigm analysis to develop a process model of science self-efficacy improvement. Through the process analysis, four cyclical phases were found in the process of enhancing SSE: 'Entering into learning science' phase, 'enhancing SSE' phase, 'adjustment' phase, and 'result' phase. More specifically, the phase of 'entering into learning science' is where students choose science track and stimulated to construct SSE. The phase of 'enhancing SSE' is where students taking a science track actively learn science and perform science activities. In the phase of 'adjustment', students come to have successful performance about learning science and performing science activities by using diverse strategies. Finally, 'result' phase indicates different appearances of students depending on SSE levels. The phases were non-linear and periodically repeat depending on situation. The core category in the selective coding was indicated to be 'enhancing science self-efficacy.' Students' SSE form by learning science and performing science activities. These finding may help better understand the behavior of students who are taking a science track by facilitating effective science learning through the increase of their SSE levels.

The purpose of this paper is to analyze the behavior of North Korea's cyber attack against South Korea since 2009 based on major international security theories and suggest South Korea's policy option. For this purpose, this paper applied the behavioral domain and characteristics of 'cyber power' and 'coercion dynamics' model, which are attracting attention in international security studies. The types of cyber attacks from North Korea are classified into the following categories: power-based incarceration, leadership attacks and intrusions, military operations interference, and social anxiety and confusion. In terms of types and means of cyber power, North Korean GPS disturbance, the Ministry of Defense server hacking and EMP are hard power with high retaliation and threat and cyber money cashing and ransomware are analyzed by force in the act of persuasion and incentive in the point of robbing or asking for a large amount of money with software pawns. North Korea 's cyber attack has the character of escape from realistic sanctions based on the second nuclear test. It is important for South Korea to clearly recognize that the aggressive cyberpower of North Korea is changing in its methods and capabilities, and to ensure that North Korea's actions result in far greater losses than can be achieved. To do this, it is necessary to strengthen the cyber security and competence to simultaneously attack and defend through institutional supplement and new establishment such as cyber psychological warfare, EMP attack preparation, and enhancement of security expertise against hacking.

This article aims to analyze main features of activation policy and compare major programmes in terms of their impact on employment performances in Korea. Since the introduction of National Basic Living Security Act in 2000, a series of activation policies have been in place for social assistance recipients, low-income employees, and youth unemployed by means of providing tailored employment and social services via in-depth counselling and case management. These activation policies carry both enabling and demanding elements: requiring programme participation in exchange for public assistance benefit receipts on the one hand, and providing various social services to remove barriers to employment through case management on the other hand. Therefore, it merits attention to analyze how various features of activation programmes affect employment outcomes, the effectiveness of delivery system and policy instruments as well. In analyzing employment outcomes of activation policy of which main characteristics lie in provision of employment and social services, this article points out the features and policy instruments of the activation policy that contribute to labor market entry of public assistance recipients and low income employees. In addition, it also delineates the determinants of exit from benefit receipts. Results from statistical analysis show that activation policy with intense employment service helps both benefit recipients and low income employees enter into the labor market at a faster rate. However, tailored social service provision enables social assistance recipients to exit from benefit receipts. These results suggest theoretical and policy relevant implication in regards to redesigning the delivery mechanisms and service instruments of activation policy.

The average acoustic distribution of American English speakers was statistically compared with the English-speaking patterns of gifted students in a Science Academy in Korea. By analyzing speech recordings, the duration time of which is much longer than in previous studies, this research identified the degree of acoustic proximity between the two parties and the predictability of English academic achievement of gifted high school students. Long-term spectral acoustic power distribution vectors were obtained for 2,048 center frequencies in the range of 20 Hz to 20,000 Hz by applying an long-term average speech spectrum (LTASS) MATLAB code. Three more variables were statistically compared to discover additional indices that can predict future English academic achievement: the receptive vocabulary size test, the cumulative vocabulary scores of English formative assessment, and the English Speaking Proficiency Test scores. Linear regression and correlational analyses between the four variables showed that the receptive vocabulary size test and the low-frequency vocabulary formative assessments which require both lexical and domain-specific science background knowledge are relatively more significant variables than a basic suprasegmental level English fluency in the predictability of gifted students' academic achievement.

Self-efficacy and entrepreneurial self-efficacy on the positive effects of entrepreneurial intention are well developed in past research but marketing self-efficacy, linked to the competencies of marketing field and is closely related to self-efficacy and entrepreneurial self-efficacy has not received enough attention on the prediction of start-up intention despite marketing and entrepreneurship are crucial when creating a start-up. Moreover, there have been several empirical studies but, most of the previous studies have focused on university students majoring in business and economics. Therefore, there is still little understanding of the effect of marketing self-efficacy on start-up intention. The purpose of this study then was to investigate the effect of marketing self-efficacy on start-up intention for college students majoring in entertainment-related studies. Questionnaires were employed to collect data from three universities in Korea. A total of 120 completed questionnaires were returned. Logistic regression analysis was used to test the hypothesis. The results indicate that marketing self-efficacy was positively and significantly related to start-up intention. The results of this study empirically confirmed that university students majoring in entertainment-related studies with high marketing self-efficacy are more likely to desire to create a start-up. These results suggest theoretical and practical implications.

This study explores variations in preferences for human and AI agents within the medical and financial services. Study 1 investigates whether there are preferential disparities between human and AI agents across these service domains. It finds that human agents are favored over AI agents in medical services, while AI agents receive greater preference in the financial services. Study 2 delves into the underlying reasons for the preference differentials between human and AI agents by assessing the significance of certain capabilities as perceived by users in each domain. The findings reveal a mediating role of perceived empathy importance in the effect of service domains on human-AI preference. Furthermore, perceived empathy is deemed a more critical capability by users for preferring human over AI agents across both service domains compared to other capabilities such as experience and agency. This research is noteworthy for elucidating the variances in preferences for human and AI agents across medical and financial services and the rationale behind these differences. It enhances our theoretical comprehension of the pivotal factors influencing preferences for human and AI agents, underscoring the significance of human experiential capabilities like empathy.

In the actantial model of Algirdas Julius Greimas, a story makes 3 kinds of relationships with 6 actants, and, in these relationships, the desires of subjects and objects are operated. And, when the subject performs its desire, there are both assistance of helper and disturbance of opponent. And, the object of desire wanted by the subject is provided by sender and receiver. Using this actantial model, this study analyzed the narrative structure of the animation 'Dalbitgungjeon', and, by rearranging the subject of capacity, examined general stream of communication. Korean animations have tried to approach using archetypes of Korean culture as motifs with various perspectives. But, it is true that, compared with foreign animations dramatized using cultural archetypes, Korean animations still have something to be desired. Thus, this study analyzed the narrative structure of 'Dalbitgungjeon' which was recently producted using archetypes of Korean culture as its motif, and, rearranging the subject of capacity, examined general stream of communication. By doing this, this study tried to search for the method of producing an animation equipped with more advanced narrative structure. Of course, narrative structure of Greimas has been studied in various aspects. However, there are still not enough animation researches using cultural archetypes of Greimas. Considering such aspects, this study focused on searching for a method of using the formation of cultural archetypes based on the analysis of fables of Greimas.

본 연구는 창업보육센터 입주기업을 대상으로 지원서비스가 성장단계별로 차이가 있을 것이라는 가정과 입주기업이 느끼는 만족도와 그에 따른 경영성과에 영향을 미칠 것이라는 가정 하에 입주기업의 니즈(needs)를 반영한 성장단계별 차별화된 효과적 지원서비스로 입주기업의 만족도와 경영성과를 높임으로써 창업성공률을 제고하기 위한 이론적 기여와 정책적 시사점을 제시하는 데 목적이 있다. 본 연구의 검증을 위하여 가설1 성장단계별 지원서비스는 정(+)의 유의한 차이가 있을 것이다, 가설2 성장단계별 만족도는 정(+)의 유의한 차이가 있을 것이다, 가설3 성장단계별 경영성과는 정(+)의 유의한 차이가 있을 것이다를 ANOVA 분석을 실시하였고, 가설4 지원서비스가 경영성과에 정(+)의 영향을 미칠 것이다, 가설5 지원서비스가 만족도에 정(+)의 영향을 미칠 것이다, 가설6 만족도가 경영성과에 정(+)의 영향을 미칠 것이다는 회귀분석을 실시하였다. 분석결과, 선행연구와 같이 지원서비스는 입주기업의 경영성과와 만족도에 영향을 미치는 것으로 나타났다. 본 연구는 창업보육센터의 성장단계별 지원서비스가 서비스의 만족도와 경영성과에 어떠한 영향을 미치고 있는지를 중소기업청 지정 창업보육센터 입주기업 174개를 표본으로 SPSS 22.0을 이용하여 검증하였다. 본 연구에서 실증분석을 통하여 얻은 연구 결과를 요약하면 다음과 같다. 첫째 성장단계별 지원서비스의 차이에 대한 차이분석 결과 정(+)의 유의한 차이가 있는 것으로 나타났다. 둘째, 성장단계별 만족도의 차이는 차이가 없는 것으로 나타났으며 성장단계별 경영성과의 차이 중 투자유치는 정(+)의 유의한 차이가 있는 것으로 나타났다. 셋째, 창업보육센터에서 제공하는 지원서비스가 입주기업의 경영성과와 만족도에 정(+)의 영향을 미치는 것으로 나타났다. 마지막으로 입주기업의 만족도도 경영성과에 정(+)의 영향을 미치는 것으로 나타났다. 결과를 종합해보면 창업보육센터의 지원서비스가 아직도 행정지원과 자금지원 등에만 국한되어 지원되고 있는 것으로 나타나 입주기업의 성장단계에 적합한 다양한 서비스의 제공이 필요함을 주지시켜 주고 있다. 또한, 성장단계별 입주기업의 만족도는 매출증가와 고용증가로 이어졌지만 아직 투자유치에는 크게 영향을 미치지 못하고 있음을 알 수 있다. 따라서 모든 입주기업에게 획일적인 지원서비스가 아닌 차별화된 지원서비스가 필요하며, 이를 위하여 창업보육센터 매니저들이 엑셀러레이터로서의 역할을 하기 위한 창업보육역량 고도화가 필요하고, 창업보육사업은 기업의 성장단계와 관련이 있으므로 입주기업의 성장단계 및 창업보육센터의 지원하는 역할과 기능에 따른 창업보육모델의 진화를 고려한 3세대, 4세대 보육모델로서의 발전된 운영정책 수립이 요구된다.
